Built-in webcam has stopped working

I purchased a Toshiba Satellite P855-S5200 laptop (just over a month ago) that runs Windows 7 Home Premium 64-bit. I have used the webcam frequently for Skype and recording videos. Today when I tried making a video call, I got an error message from Skype that no camera was detected. I checked in Device Manager and the camera was not listed there. I've tried doing a system restore back to when I know the camera was working. That did not work. What could have caused this problem? What can I do to resolve it?

Sounds like your web cam went bad. If you have already tried a system restore point. I doubt downloading drivers would solve the problem. Your best bet would be to have it service. You are still under warranty.
